METALLIC CORE FOR RAILWAY-TIES.

Application tiled November 20, 1907.

Specification of Letters Patent.

Patented Sept. 22, 1908.

Serial No.-403,021.

To oil whom it may concern:

Bo it known that I, XVxLLmu B. Wins"- nnooii, a citizen of thel United States, residing at. (.`litl`, in the county of Flo vd and State of Kentucky, have invented certain new and useful improvements in Metallic Cores for:

ltail\-:av-'l`ies, of which the following is a. specification.

'lhis` invention relates to railway tics, and pertains especially to the. class of such ties composed of concrete., cement or other suitable material having a metal core.

'l`be object of the invention is to provide in concrete cross-ties, and especially bridge and switch ties, a. metal core of such novel and peculiar construction as to permit passage tberetlnough of concrete or other suitable plastic material and to hind the. same, and to leave sutiicientmetal to brace and hold such material within` and without the core.

A further object of the invent-ion is to provide. a metal core for railwa \v cross-ties having a pair of slots or openings for suitable rail-blocks or chairs, and provided throughout with a series of perforations or apertures.

Other objects, advantages and improved results are obtainable b v means of the. special shape and construction of the core as will be hereinafter full)v described and pointed out in the claims to follow:

ln the accompanying drawings forming part of thi'sapphcationI-Figurc 1 is a perspective view of atie embodying the invention. Fig. l is a top view of the. core. Fig. 3 is an enlarged cross section of the core. Fig. 4'is a longitudinal .section on tho line 'J?/, Fia- 1- 'lhe same. reference numerals denote the same parts throughout the several views of the drawings.

The tie l i composed of concrete, cement or other suitable material adapted to be carried within and wit-hout a core 2.

The metal core 2 is preferably concaved at the top and its sides are convexed so as to presentl a tubular sha ed core. Two slots or openings 3 are. ma e through tho top of the core for the insertion of rail-blocks 4, and each end of' tite core has a hole. 2 through the bottom and top for a suitable bolt A series of perforations 6 is made. throughout i the. sides, bottom and between the. slots 3 in the. top of the core. These. perforations alternate so as to leave sufficient met-al between them for maintaining proper stiitness and strength in the core.

Atlthe. inner enoof the slots 3 and under an over-hanging lip 7, at the. inner end of an opening 7, a cavity 8 is formed in the concrete for the wedge-shaped end of the blocks 4, and a tie-bolt tl extends through the other end of the blocks to hold them in the tie.

It is obvious that the perforations form a passage for the concrete m applying the latter to the core; that the side perforations hold the concrete in a solid body within and wit-bout the core; and that by reason of such pcrforations an unusual solid body of concrete is maintained throughout the coro.

Having thus described my invention what I claim as new and desire to secure by Letters Patent; is:-

l. A coro for concrete railway ties, comprising tubular shaped metal having railbloc-k slots, and a series of perforations throughout its sides, bottom, and top between said slots.

alternating perforatlons between the slots,

perforated sides, and a series of alternating perforations in the bottom of the core.

In witness whereof 1 hereunto set my hand in thel presence of two witnesses.
